That episode reminds me of a time in college.  I set my favorite pair of sunglasses on the roof of a friend's car and forgot about them.  He pulls out of the parking lot and we hear them slide off onto the road.  He stops, I jump out, and am about to go grab them.  In an unbelievable Costanza moment, this giant semi truck is coming down the road.  Not an SUV, not a pickup, but a friggin' semi.  You know the rest of the story...
